Definitions

  • the present invention relates to liners for boxes used for collection of cat urine and feces.
  • a proliferation of liners have been proposed for use in boxes used for collection of cat urine and feces ("cat boxes"). Some employ the use of a fluid- impermeable first layer for lining the cat box. a sorbent second layer smaller than the first layer, positioned atop the first layer at least in the bottom of the box, and a claw- resistant third layer atop the sorbent layer and bonded to a peripheral region of the first layer.
  • a liner typically requires initial adhering to the cat box by the use of adhesives, for instance, and must be done in a fairly precise manner. This is a somewhat tedious, but not unpleasant, task. In contrast, the task of detaching the liner from the box when the liner has become soiled from cat urine and feces is not only tedious, but unpleasant owing to the odors of cat urine and feces.
  • a cat-box liner may be specially configured to achieve a stretch fit to the corners of a cat box. This require special manufacturing steps to accomplish, and typically results in a liner suited for use with cat boxes in a fairly narrow range of dimensions.
  • An exemplary embodiment of the invention provides a liner for a cat box having sides extending upwardly from a bottom to a vertical height.
  • the liner comprises a bag for placement in the cat box.
  • the bag comprises a bottom portion for lining the cat box, and a contiguous top portion.
  • a fluid-impermeable layer is placed within the box, located within the bottom portion of the bag and bonded to the bag.
  • a sorbent layer is placed above the fluid-impermeable layer.
  • a claw-resistant layer is placed above the sorbent layer and affixed to the fluid-impermeable layer so as to stiffen the affixed layers, whereby they tend to stay in place in the cat box.
  • the top portion of the bag drapes over the sides of the box for a drape length and provides ballast for helping the liner to stay in place.
  • cat-box liner accommodates cat boxes with a broad range of dimensions. It can be installed and removed easily. Because it can be removed quickly, the unpleasant nature of its removal is minimized.
  • Fig. 1 is a perspective view of a typical cat box.
  • Fig. 2 is a perspective view of a cat-box liner positioned atop the cat box of Fig. 1.
  • Fig. 3 is a side sectional view of a portion of the cat box with the liner installed.
  • Fig. 4 is an enlarged, fragmentary, cross-sectional view of one form of an outer bag used in the invention.
  • Fig. 5 is a side view of the liner in a suitable state for discarding after removal from a cat box.
  • Fig. 1 shows a typical cat box 10 for collecting the urine and feces of a cat.
  • Box 10 has sides 12a, 12b, 12c and 12d extending to a vertical height above a bottom 14.
  • Fig. 2 shows a cat-box liner 16 of the present invention in position on box 10. It includes an outer bag whose top portion 18 drapes over the sides of the box. As shown, the top portion includes a drawstring 20, partially contained within a tubular sleeve 18a. Although not shown, the opposite side of tubular sleeve 18a preferably has an opening for access to another portion of the drawstring.
  • Fig. 3 shows a portion of a portion of cat box 10, with liner 16 installed in the box.
  • a bottom portion 19 of the outer bag preferably rests directly on the inside of box 10, and adjoins top portion 18 of the bag at the top of side 12d of the box, for instance.
  • a fluid-impermeable layer 22 is positioned preferably directly atop bag portion 19.
  • the upper, e.g., 2 to 6 centimeter peripheral portion of layer 22 is preferably attached to bag portion 19 by glue or heat sealing.
  • the sealing is substantially fully around a peripheral region of layer 22.
  • a sorbent layer 24, which may be conventional per se, is placed above layer 22. It preferably covers at least the bottom of box 10 and extends slightly upwards at the sides of the box.
  • a fluid-permeable, claw-resistant layer 26 which may be conventional per se, is positioned above sorbent layer 24 and any tissue layer (not shown). It is affixed to layer 22 in a majority of 3 -centimeter (or 1.5 centimeter) squares of areas of adjacency of the layers, preferably directly or through an intermediate layer. This results in stiffening of the affixed layers so that they tend to stay in place in the box. It may also be affixed to the sorbent layer.
  • a preferred bonding of layer 26 to layer 22 is heat- induced bonding in thin parallel strips (e.g., under 1 millimeter) spaced apart by about one centimeter.
  • Cat litter 28 may be placed atop liner 16 for collection of cat feces.
  • fresh cat litter is provided with the liner, to even further simplify the task of collecting and disposing of cat wastes.
  • top portion 18 of the outer bag drapes over the sides of the cat box. Preferably it drapes substantially straight downwardly. By so draping, top portion 18 provides ballast, or weight, for helping liner 16 stay in place in the box.
  • the length of draping is more than half the vertical height of the sides; more preferably, it is more than three-quarters the vertical height; and still more preferably it is substantially the full vertical height of the sides.
  • a single size of outer bag can accommodate cat boxes of different dimensions where fluid- impermeable layer 22 extends sufficiently up the sides of a cat box, e.g, typically 6 to 10 centimeters, to prevent fluid from reaching the cat box.
  • the outer bag can be reinforced in its construction with fibers contained within a flexible matrix of plastic, for instance. Referring to Fig. 4, such reinforcing fibers are shown at 30 in bag portion 19.
  • the fibers may be made of woven or unwoven synthetic materials, such as nylon, or natural materials.
  • the stiffness of the inventive liner arising from the various aspects of its construction described above helps keep the liner in place in a cat box. This is advantageous whether or not the box is used with an additional cover (now shown), such as may be placed atop the sides of the cat box.
  • the inventive liner more readily stays in place during the process of placing a cover on the box.
  • Fig. 5 shows a cat box liner 16 removed from the cat box, and with the drawstring 20 of the bag tightened. This allows very quick removal of the liner and its contents, with great ease and with little likelihood of spilling the contents of the liner (e.g., dirty cat litter). It is preferred that top portion 18 be long, as described above. This facilitates complete closure of the bag as shown in Fig. 5. To the contrary, with top portion 18 having a short length, it has been found that the bag cannot easily be completely closed at the top.
  • fluid-impermeable layer 22 may comprise a thin sheet of plastic material, such as polypropylene or polyethylene.
  • Sorbent layer 24 may comprise, for instance, the sorbent material described in U.S. Patent 4, 117, 184.
  • Claw-resistant layer 26 may comprise, for instance, strands of polyester or polypropylene, which collectively achieve structural integrity through bonding at the intersections of the strands.
  • a surfactant is preferably used to assure that layer 26 is permeable or semi-permeable to liquid.
  • Bag 18 preferably comprises thin plastic material, which may incorporate fibers as described in connection with Fig. 4.

Abstract

La présente invention concerne une garniture de caisse à litière pour chat comprenant des côtés s'entendant verticalement vers le haut à partir d'un fond. La garniture comprend un sac à disposer dans la litière pour chat. Ce sac comprend une partie fond permettant de garnir la litière et une partie supérieure contiguë. Une couche imperméable au liquide est placée dans la boîte, est disposée sur la partie fond du sac et est reliée à ce sac. Une couche sorbante est placée sur la couche imperméable au liquide. Une couche résistant aux griffes est disposée sur la couche sorbante et est fixée à la couche imperméable de manière à raidir les couches fixées, tendant ainsi à les maintenir en place dans la litière. La partie supérieure du sac retombe sur les côtés de la boîte sur une certaine longueur, ce qui fournit un lest permettant de maintenir la garniture en place.
